O laasaga o le gaosiga o faʻamaʻi faʻamaʻi: faʻafefiloi le sulfate siliva, amproof, ma le tele-oxides i le faʻatusatusa, ona faʻaopoopo 1 taimi le voluma o vai faʻafefe, fetuunai le pH le tau o le sulfuric acid ma le ammonia vai i le 6.5 i le 7, ona faʻaopopo lea o le sodium silicine ma le sodium siliconate ma faʻatusatusa i vaega.O malala paʻepaʻe e uliuli, faʻavevela ma faʻafefeteina e fai ai le fofo tutusa;faʻafefe i totonu o le vai taele ma faʻafefete le vaifofo e faʻamago, faʻagogo i le 100-120 ° C mo le 6 i le 8h, ona tao lea mo le 3 i le 5h i le 400 ~ 450 ° C. 2. Sauniuniga o le N-hydroxyethylpylpyline (NHP) 1) Faafefiloi le γ-butanol, tasi ethanol, ma le amonia i le fua faatatau o le 1.2: 1: 0.2, ma tali i le 0.5MPa ma le 40 ° C. , Fai se vaeluagalemu;2) Faʻaopoopo le mole mole sieve o le 0.1WT% ma le 0.1WT% o le dilateyl dihal ether e faʻateleina ai le vevela i le 180 ° C e faʻagata ai i le 12h i se tulaga taofia;mea ua faamatalaina e pei ona faamatalaina;o le a le mea ua taua?O le sieve mole o le 10xchemicalbook molecular sieve poʻo le 13X molecular sieve.O lenei metotia ua filifilia e pei o 10x molecular sieves;3) decompression distillation, o le gaogao o le 0.095MPa, ma aoina le distillation o le vaipuna o le 210 i le 216 ° C. Pyrodorrone;3. Le tali dehydration o le N-hydroxyetylpinol e faia le distillation sikoa maua i le sauniuniga o le N-hydroxyethylpinols i le ausa, fefiloi ma alkaline kasa, acetylene kasa, ma nitrogen e maua kasa paluga mea mata.Ole fua faʻafefiloi ole 1 : 0.5: 0.1: 0.1;Fai le kasa fa'afefiloi mea mata i lalo o le tulaga o se fa'amoe fa'amaufa'ailoga o le fa'agata fa'amama i le vevela o le 350 ° C, le mamafa o le 0.01MPa ma le saoasaoa o le kesi o le 50-300H-1, ma le fa'amama o le fa'amama i le fa'amaumau. moega reactor O le faʻamalosi e faʻamafanafanaina i le 390 ° C. A maeʻa ona oʻo atu le faʻamamago o le vai i le paleni, o le N-ethylene cephalopicone (NVP) oloa e faʻateʻa mai se faʻamaufaʻailoga moega.O kasa alkaline e le itiiti ifo ma le tasi o ammonia, methylemine, dihamine, trothalmine, ma ethimine.Fa'aaoga metotia su'esu'e chromatography kasa, fa'avae i luga ole γ-butthite e pei o le tulaga i totonu, ethanol e pei o solvents, su'esu'eina le N-ethylene cheedone oloa saunia e lenei metotia, fuafuaina le fua faatatau o le liua o le NHP, NVP selectivity, NVP tupe maua, o le vaega o le kesi. vaega vaega, lea kasa vaega vaega vaega vaega vaega, lea kasa vaega vaega tulaga Chromatographic suega tulaga: TCD detector, koluma uamea stainless, poly acetic glycol tannite dilate fofo faaleleia, ua uta nitrogen, silicanerization 102 eseesega paepae, gasification potu vevela 280 ° C, TCD detector vevela 165 ° C, koluma, koluma, koluma Le vevela o le 190 ° C;fuafuaina e ala i le au'ili'iliga o le kesi chromatography: NHP fua faatatau liua o le 92.8%, NVP filifilia 91.5%, ma le NVP tupe maua o le 85.6%.
